DEFINITION

Classification: 60/369

(under subclass 325) Apparatus having a pump or other means, not otherwise provided for, to place a gaseous or liquid motive fluid in a condition so that subsequently it may be expanded or contracted or otherwise cause the activation of a transducer or motor means having (1) a cyclically operable oscillatable or linearly reciprocable work output member and (2) means to control the flow of said motive fluid to cause said work output member to do work cyclically.
